Benefits of technology

[0008]An advantage of some aspects of the invention is to provide an ink jet recording method capable of recording an image having a good metallic luster on a recording medium.

Problems solved by technology

It is difficult to form an image having a sufficient metallic luster on a recording medium, such as a sheet of plain paper, having substantially no coat layer by the ink jet recording method.
Since plain paper absorbs ink, it is difficult to fix a metal powder on a printing surface of a sheet of plain paper.

examples

[0116]The present invention is further described in detail with reference to examples and comparative examples. The examples are not intended to limit the scope of the present invention.

[0117]Recording media used in the examples and comparative examples were sheets of plain paper, Xerox 4024, available from Fuji Xerox Co., Ltd. The plain paper sheets included no coat layer.

[0118]First ink compositions and second ink compositions were prepared as described below. The first and second ink compositions were measured for viscosity with a viscometer, AMVn, available from Anton Paar GmbH.

[0119]The following mixture was used to prepare a first ink composition A1: a solvent mixture of 20.0 parts by mass of γ-valerolactone, 65.5 parts by mass of diethylene glycol diethyl ether, and 10.0 parts by mass of tetraethylene glycol monobutyl ether.

[0120]The solvent mixture and 2.0 parts by mass of a dispersant, Solsperse 32000, available from Avecia K. K. were mixed together with a dissolver at a ra...

Abstract

An ink jet recording method for recording an image having a metallic luster on a recording medium with an ink jet recording apparatus includes forming an underlayer on the recording medium by applying droplets of a first ink composition containing a first thermoplastic resin to the recording medium and also includes forming a metallic luster layer on the underlayer by applying droplets of a second ink composition containing a metal pigment and a second thermoplastic resin to the underlayer. The glass transition temperature of the first thermoplastic resin is lower than or equal to the glass transition temperature of the second thermoplastic resin. The underlayer is formed at a temperature higher than the glass transition temperature of the first thermoplastic resin.

Description

BACKGROUND[0001]1. Technical Field[0002]The present invention relates to an ink jet recording method and a record.[0003]2. Related Art[0004]In recent years, there have been increasing demands for prints having images, formed on printing surfaces, having a metallic luster. The following methods have been used to form such images having a metallic luster: for example, a foil stamping printing method in which a recording medium having a flat printing surface is prepared and a metal foil is pressed against the recording medium, a method in which a metal is vacuum-deposited on a plastic film having a smooth printing surface, and a method in which a recording medium is coated with a metal pigment ink and then subjected to pressing.[0005]Meanwhile, an ink jet recording method is a process in which printing is performed in such a manner that droplets of an ink composition are ejected and applied to a recording medium such as a sheet of paper. The ink jet recording method has an advantage th...
